Disclosed is a multi-needle module used for a sewing machine, capable of being attached and installed on an existing sewing machine, and capable of conveniently refitting an existing sewing machine into a multi-needle sewing machine. The multi-needle module is not limited to a twin-needle structure and can be equipped with three needles, four needles or even more needles according to needs, solving the problem of a single-needle sewing machine and a twin-needle sewing machine having insufficient varieties of upper thread colour when sewing a pattern and thus requiring manual exchange of threads. The multi-needle module guides each needle (4) by means of a first horizontal guide groove (11) and a second horizontal guide groove (12), and feeds a specific needle into a snap-groove (5a) of a needle driving block (5) by means of a driving mechanism, and has the advantages of a simple structure and automated control. |
